Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616212, here are decompositions:

13 + 8616199 = 8616212
43 + 8616169 = 8616212
61 + 8616151 = 8616212
193 + 8616019 = 8616212
223 + 8615989 = 8616212
229 + 8615983 = 8616212
271 + 8615941 = 8616212
331 + 8615881 = 8616212

Showing the first eight; more decompositions exist.
